Trang 6Introduction
CEN/TC 190 "Foundry Technology" has prepared a series of material standards covering the following cast irons:
grey cast irons [1];
malleable cast irons [2];
spheroidal graphite cast irons [3];
ausferritic spheroidal graphite cast irons [4];
abrasion resistant cast irons [5];
austenitic cast irons [7];
compacted (vermicular) graphite cast irons [8];
low alloyed ferritic spheroidal graphite cast irons for elevated temperature applications [9]
In order to assist manufacturers and purchasers to prepare proper contractual arrangements and prevent misunderstanding, CEN/TC 190 approved the preparation of a series of standards covering technical delivery conditions These have been prepared as separate parts
This European Standard covers the additional technical delivery conditions for all the cast iron materials, e.g optional information, manufacturing process, welding operation, additional requirements regarding the condition of the casting, test methods
This European Standard cannot be used alone for compiling a specification for ordering and supplying iron castings, but as a complement to EN 1559-1
The symbol ● against the clause reference indicates that the requirements of that clause of EN 1559-1 have
to be met
Trang 71 Scope
This European Standard specifies the additional technical delivery conditions for castings made from all cast iron materials
This European Standard applies to iron castings produced in sand or permanent moulds or by centrifugal casting, continuous casting or investment casting

NOTE Because some non-destructive testing methods are more suitable than others for iron castings, they should be discussed under the technical and economical aspects before agreement between the manufacturer and the purchaser
Trang 107.3.3.2 ●
7.3.3.3 The selection of a non destructive testing method is dependent on the thickness and material of the casting and the position, orientation and size of possible discontinuities in the relevant section
Different acceptance criteria can be specified for different areas of the same casting (e.g marked zone and unmarked area) Moreover, for the same area of the casting different acceptance criteria can be specified according to the non destructive methods selected
For all non destructive testing methods, the acceptance criteria (discontinuity levels) can be graded with increasing number and/or extent of indications
Unless specifically agreed, discontinuities revealed on cast surfaces which are to be machined, are not to be regarded as discontinuities, when these discontinuities are totally removed by machining
Guidelines for the specification of acceptance criteria for discontinuities are given in the informative Annex A
7.3.3.4 If applicable, the roughness of the cast or grinded surface shall be specified
EN 1370 shall be used to specify the acceptance levels and shall be subject of an agreement between the manufacturer and the purchaser by the time of acceptance of the order
Guidelines for the specification of acceptance criteria for the surface condition are given in the informative Annex B
7.3.4 ● Condition of the casting
